 |
|
Hi,
I have a problem extending the lvm I use for the recordings on a mythtv box. Here is what I have:
| Code: |
mythtv ~ # vgexport -a
Volume group "mythvideo" successfully exported
mythtv ~ # vgimport -a mythvideo
No arguments permitted when using -a for all.
mythtv ~ # vgimport -a
Volume group "mythvideo" successfully imported
mythtv ~ # vgchange -a y
1 logical volume(s) in volume group "mythvideo" now active
mythtv ~ # vgdisplay
--- Volume group ---
VG Name mythvideo
System ID
Format lvm2
Metadata Areas 2
Metadata Sequence No 10
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 0
Max PV 0
Cur PV 2
Act PV 2
VG Size 134.81 GB
PE Size 64.00 MB
Total PE 2157
Alloc PE / Size 2157 / 134.81 GB
Free PE / Size 0 / 0
VG UUID QT42d2-W9ML-0uVp-qi4U-4yKR-lY65-6U0mMj
mythtv ~ # vgscan
Reading all physical volumes. This may take a while...
Found volume group "mythvideo" using metadata type lvm2
mythtv ~ # lvscan
ACTIVE '/dev/mythvideo/video' [134.81 GB] inherit
mythtv ~ # mount -a
mythtv ~ # df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda3 6833440 4695468 2137972 69% /
/dev/hdb1 9765248 272 9764976 1% /myth/mythburn/temp
none 111364 0 111364 0% /dev/shm
none 111364 0 111364 0% /dev/shm
/dev/mythvideo/video 72971456 65534992 7436464 90% /mnt/video

I have formated and initialised with pvcreate the added partition, I get no error messages, but as you can see, there are a couple of Gigs missing 
Please, what did I forget to do?

| It looks like you correctly created the physical volume from the new disk, added that to the volume group and then added the new PEs to the correct logical volume. So now your lvm "partition" is bigger but I guess you haven't yet resized the filesystem on that partition. for details see http://www.linux.org/docs/ldp/howto/LVM-HOWTO/extendlv.html |

Than you so very much. Of course! I'll try tonight!
